Sony PlayStation 4 Early Prototype Controller

Very early prototype of the Dualshock 4 controller. Differences include: it using a mini USB instead of the micro USB, the D-Pad is similar to the PS Vita's D-Pad, the light bar is a different shape, it has PS3 triggers, the back has a concave area, the "options" and "share" buttons are rectangular, the touchpad is a flat, texture-less surface, and there is no docking port on the bottom, only the headphone jack. Apparently it can connect to a PS3.
